Default boundary conditions for wind driven flow

Hello everyone,

I'm stuck in a problem since a week and I can't figure out how to proceed.

I'm trying to simulate a wind driven flow, I have a domain with two phases, water and air, and I apply a constant velocity in the "air" domain. I want to see how water responds to this. Briefly, I want to describe the onset of the waves.

Since I only have a patch for inlet (for outlet and so on) I'm using multiphaseEulerFoam, rather than interFoam, to avoid splitting the patches. The problem is... my domain is emptying! The water flows out of the domain and I can't keep it inside in any way..

Does anyone have experienced this or have any clue on how the boundary conditions should be set to prevent this problem?

Thank you in advance!
